LIS 504 - Sequence effects

A researcher needs to remember
that earlier events can affect later events.
What information or questions are presented earlier
in a questionnaire or interview, for example,
can affect responses to later questions.
The order in which the earlier information or questions
were presented can also have an impact.

Primacy effectThe first stimulus is often remembered
better than other stimuli.

Recency effectThe most recent stimulus is often remembered
better than other stimuli.

Serial effectA questionnaire can lead later responses
by establishing a certain tone at an earlier stage.
